(CR,CD,CU,CR,CD,CU) Used to change night to day and day to night at any time! Also freezes the undead zombies and mummies. Go to the Kakariko Graveyard at night and go to the large gravestone in the back. Check the two gravestones on either side of it and fight the Poe brothers. Once they are defeated, play Zelda's Lullaby to open the Royal Tombstone. Fall down the hole, kill all the bats to open the doorway, and go through the tomb to learn the Sun's Song.
